An inverter is one of the most important pieces of equipment in a solar energy system. It's a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses.The inverter is the heart of your PV system. The entire investment’s rate of return in the form of generating renewable energy from solar power depends on this inverter.

What are inverters?
Solar panels convert light to electrical direct current (DC) energy. However, the electrical power in use is alternating current (AC). Inverters transform the DC energy that solar panels collect into AC energy.

Difference between central or String inverters and Microinverters?

Central (or string) inverters work by linking your solar panels together with “strings.” These strings are then connected to a single inverter. Conversely, microinverters pair each panel with its individual inverter. Microinverter systems are wired in parallel versus being wired in a series like string inverters.
